Match List I (Molecules) with List II (Boiling points) and select the correct answer

	List I		List II
(A)	${\mathrm{NH}}_3$	(i)	290 K
(B)	${\mathrm{PH}}_3$	(ii)	211 K
(C)	${\mathrm{AsH}}_3$	(iii)	186 K
(D)	${\mathrm{SbH}}_3$	(iv)	264 K
(E)	${\mathrm{BiH}}_3$	(v)	240 K

The boiling point depends on the molecular mass of the molecules. The heavy molecules have a large number of electrons and have strong Van der Waals. Therefore, required higher energy to overcome these forces, therefore generally, the boiling point of large molecules is high. 

Among the given compounds, the boiling point of BH₃ is the highest, and the boiling point of SiH₃ is the second-highest because both are heavy molecules. But there is an exception, NH₃ has hydrogen bonding, therefore the boiling point of NH₃ is higher than AsH₃ and PH₃. The boiling point of PH₃ is lower than AsH₃ because As has a larger size than P. Boiling point trend comes out to be:

${\mathrm{BH}}_3>{\mathrm{SbH}}_3>{\mathrm{NH}}_3>{\mathrm{AsH}}_3>{\mathrm{PH}}_3$

The correct order according to the given table is:

$\mathrm{A}-\mathrm{v}, \mathrm{B}-\mathrm{iii}, \mathrm{C}-\mathrm{ii}, \mathrm{D}-\mathrm{iv}, \mathrm{E}-\mathrm{i}$
